I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

Yang Hongbo immediately used a thousand-year cultivation card, which greatly increased his cultivation to the peak of the Nascent Soul stage. He then took out a Void Realm puppet and stuffed 50 billion top-grade spirit stones into the space inside its body. Only then did a peak Returning Void Realm demon beast appear in the space.

This monstrous beast had been imprisoned in this space for countless years. Just as it was able to relax and was howling, a tremendous pressure suddenly struck. After only a slight tremor, the monstrous beast vanished from the world.

At this moment, the artifact spirit appeared in the space. Looking at the Void Realm puppet, he said in surprise, "I never expected you to have a Void Realm puppet. It seems the next level is useless to you. I wonder if the third level's realm test will be of any use to you. Just go straight to the third level!"

After saying that, he waved his hand again, and Yang Hongbo appeared in a bizarre world. In a flash, the world transformed into a scene from Yang Hongbo's previous life with his first love.

This was after they graduated. Due to family reasons, the two were separated. Yang Hongbo took some time to go to his girlfriend's workplace and lived with her for a week. But this time, the separation turned into a real breakup.

Yang Hongbo will never forget his first love, but he also knows that this is an illusion. His girlfriend happily holds his hand, and he first strokes her cheek, then moves his hand down to her neck. Suddenly, with a "crack," his girlfriend's head droops down.

The illusion shattered, and Yang Hongbo returned to the mountaintop. The spirit of the artifact happily said to him, "Congratulations, my little master! This secret realm is now yours!"

Yang Hongbo activated his magic technique, and after a slight tremor, the entire secret realm shrank into a small ball, which flew into his mind's sea.

Yang Hongbo appeared in the cave, while the other four were still waiting outside. Upon seeing him, they excitedly asked, "Master Yang, you succeeded?"

"Yes, I am now the master of the secret realm!"

"Um, Venerable Yang, we're planning to move our family to the area next to your Yang family's Qingmang City. Is that alright?"

"Of course, that's possible. Anyway, the area is so big, you can build a few fortified cities there, and we can form a great alliance in the wilderness."

Everyone started heading home, while Yang Hongbo also diverted a wisp of his mind into the system. His system points surged by five trillion after acquiring the secret realm space, indicating that there were many rare and precious treasures inside!

Halfway there, everyone parted ways and went home. As soon as Yang Hongbo returned to Qingmang City, he immediately entered the Yang family's small world, took out a seventh-order spiritual vein, and injected it into the original spiritual vein. Immediately, the treasure tree shot up again, reaching a height of over a thousand meters, and the diameter of its roots reached a hundred meters.

Meanwhile, the mountains in the small world grew to tens of thousands of meters high again, and dozens more peaks appeared. Yang Hongbo also made countless teleportation arrays and set up dozens of teleportation arrays on each mountain peak.

These teleportation arrays are mainly for ordinary people to use, since cultivators can fly and go wherever they want.

Yang Hongbo then deployed the three large formations he won in the lottery in Qingmang City. These three eighth-order formations could defend against attacks from Saint Emperor-level experts at the peak of the Void Realm.

Then, from the twenty-two fifth- and sixth-order spiritual veins he obtained, he took out a fifth-order spiritual vein and placed it in a small world he had purchased from the system. He then divided it into hundreds of thousands of cave dwellings, ranging from Qi Refining Stage to Nascent Soul Stage. This small world replaced the thousands of ordinary cave dwellings in the original cave dwelling rental area, which stunned the cultivators in the city.

This is an incredible benefit! As long as the cultivators in the city have the ability, they don't need to go anywhere else; they can advance to the Nascent Soul stage right here.

The spiritual energy emanating from the city has reached the third level. This spiritual energy can slowly repair the bodies of ordinary people, not only extending their lifespan but also enabling them to give birth to more offspring with spiritual roots.

By the time all this was done, a month had passed, and the four people who had teamed up with Yang Hongbo had already brought their families to the vicinity of Qingmang City.

They were the Zhou family, the Wu family, the Zheng family, and the Wang family. These four families, centered on Qingmang City, started building cities in four directions, each two hundred miles away from Qingmang City.

Each of their families has one to two million people, which is more than enough to form a small city even without outsiders joining.

Yang Hongbo stood atop the highest city tower in Qingmang City, overlooking the four garrison cities under construction in the distance. The Zhou, Wu, Zheng, and Wang families were methodically directing their clansmen to move stones, build houses, and construct city walls—a truly magnificent sight.

At this moment, Zhou Zhentian, the head of the Zhou family, flew to the city tower where Yang Hongbo was located, cupped his hands and bowed to Yang Hongbo, saying, "Heavenly Venerable Yang, the construction of the four garrison cities is now taking shape, but we still need your advice on the subsequent planning."

Yang Hongbo smiled and turned to Zhou Zhentian, saying, "Clan Chief Zhou, there's no need to be so polite. Now that we've formed an alliance, we're all one family. The planning of these garrison cities must consider both the independence of each clan and the overall defense and development of our alliance. I think we could establish a teleportation hub in the center of each garrison city, connecting it to Qingmang City and other garrison cities. This would greatly facilitate the transportation of supplies and the movement of people."

Zhou Zhentian's eyes lit up, and he nodded, saying, "Yang Tianzun's plan is brilliant. In this way, our alliance will be like a tightly knit whole, and we can react quickly no matter what situation we encounter. However, the construction of this teleportation hub will probably require a lot of resources and manpower."

Yang Hongbo waved his hand and said, "You don't need to worry about resources. My Yang family will provide some, and the rest will be shared by the four families. As for manpower, we will select some clansmen who are proficient in array formations from each family, and I will teach them some advanced array formation knowledge. I think building this teleportation hub will not be difficult."

Zhou Zhentian said gratefully, "Thank you for your support, Yang Tianzun. With you in charge of the alliance, our four families can definitely develop with peace of mind."

As they were talking, Wu Xiong, the patriarch of the Wu family, flew up as well. He was a burly man with a loud voice: "Heavenly Venerable Yang, the defenses of this city cannot be ignored. Although this desolate land seems peaceful now, there are countless forces secretly eyeing us covetously."

Yang Hongbo nodded solemnly and said, "Clan Chief Wu is absolutely right. I have already made plans. I will set up some defensive formations around each city, using the eighth-order killing formation as the core, and combine them with the formations we obtained from the secret realm. Even if a Saint Emperor-level expert attacks, we can hold them off for a while."

Upon hearing this, Wu Xiong was overjoyed and said, "With such a thorough arrangement by Heavenly Venerable Yang, the safety of our Weicheng is no longer a concern."

Zhou Zhentian gave a thumbs up and exclaimed, "Yang Tianzun has such great foresight, we admire him greatly. With you leading our alliance, we will surely be able to carve out a place for ourselves in this wild land."

At this moment, Zheng Wanqing, the head of the Zheng family, and Wang Tianhao, the head of the Wang family, also arrived together. Zheng Wanqing was graceful and had an exquisite face. She said softly, "Master Yang, the development of this alliance, besides defense and construction, cannot lag behind in commerce. Our four families each have their own industries of expertise. If we can integrate them to form a complete commercial chain, it will surely make our alliance's economy prosperous."

Yang Hongbo's eyes lit up, and he said, "Clan Chief Zheng is absolutely right. My Yang family has some unique elixirs and magical treasures. We can set up a trading market in Qingmang City for all families and outsiders to trade. At the same time, we can form a caravan to buy and sell supplies in various parts of the wilderness. In this way, we can not only promote the alliance's economy, but also keep abreast of the outside world's developments."

Wang Tianhao was a generous man, and he said loudly, "Master Yang, leave the matter of forming this caravan to my Wang family. My Wang family has many members, and many of them are good at business. We are sure to make this caravan a great success."

Yang Hongbo nodded in satisfaction and said, "Alright, then I'll have to trouble Clan Chief Wang. However, the safety of this caravan is also of utmost importance. I will arrange for some experts to protect it secretly and ensure its safety."

After the discussion, everyone went back to make their own arrangements. Under Yang Hongbo's overall planning, the construction and development of the alliance proceeded vigorously.

A month later, the four fortified cities were basically completed, and the teleportation hub was also successfully finished. Yang Hongbo personally tested the teleportation array's effectiveness. He stood in the teleportation array, and with a flash of light, he appeared at the teleportation hub of another fortified city, drawing gasps of amazement from everyone.

Meanwhile, a bustling trading market opened in the center of Qingmang City. A dazzling array of elixirs, magical artifacts, and spiritual herbs attracted numerous cultivators to trade. Caravans, organized by the Wang family, also embarked on their journey, traversing the desolate lands.

As time went on, the alliance grew stronger and more renowned. Many smaller factions came to join them, hoping to develop under the alliance's protection. Yang Hongbo treated all these factions equally, granting them appropriate status and resources based on their strength and contributions.

However, the alliance's development was not without its challenges. One day, Yang Hongbo was cultivating in the Yang family's small world when he suddenly received an alarm from the artifact spirit: "Little master, a powerful enemy is approaching the alliance."

Yang Hongbo immediately opened his eyes, and in a flash, he appeared atop the main city tower of Qingmang City. At that moment, dark clouds filled the distant sky, and a powerful aura swept towards them. A short while later, a group of cultivators dressed in black robes appeared above the alliance.

The leader was a powerful expert at the peak of the Returning Void Realm, a god-level expert. He looked coldly at Yang Hongbo and said, "You are Yang Hongbo, the leader of this alliance? I've heard you are quite strong. Today I'd like to test your skills."

Yang Hongbo remained calm and asked, "Who are you? Why have you invaded my alliance without cause?"

The powerful being at the God-level laughed and said, "I am the Black Demon Ancestor, the Sect Master of the Black Demon Sect. Your alliance has developed so rapidly that it has threatened the position of my Black Demon Sect. Today, I will completely destroy your alliance."

Yang Hongbo snorted coldly and said, "Black Demon Ancestor, if you leave now, I might spare your life. Otherwise, don't blame me for being impolite."

The Black Demon Ancestor was furious and said, "What arrogance! Today I will show you the power of my Black Demon Sect." With that, he waved his hands, and streams of black demonic energy rushed towards Yang Hongbo.

Yang Hongbo remained calm and activated his magic, instantly turning three eighth-order grand formations to completely block the Black Demon Ancestor's attacks. Upon seeing this, the Black Demon Ancestor's expression changed, and he said, "I didn't expect you to possess such powerful formations, but today you still cannot escape death."

Having said that, he launched another attack, simultaneously summoning a horde of Black Demon Puppets that charged towards the alliance's city. Yang Hongbo sneered, saying, "Well done." With a thought, a Void Returning Realm puppet appeared on the battlefield, engaging in fierce combat with the Black Demon Ancestor. At the same time, he flashed forward, charging towards the Black Demon Puppets.

The Void Returning Realm puppets and the Black Demon Ancestor engaged in a breathtaking battle in the air, the powerful energy fluctuations causing cracks to appear in the surrounding space. Yang Hongbo, relying on his peak Nascent Soul cultivation, was also locked in a fierce and evenly matched struggle with the Black Demon puppets.

Just then, Elders Zhou Zhentian, Wu Xiong, Zheng Wanqing, and Wang Tianhao arrived with the alliance's experts. They joined the battle and engaged in a fierce fight with the Black Demon Sect cultivators.

After a fierce battle, the Black Demon Sect cultivators gradually lost ground. Seeing that the situation was hopeless, the Black Demon Ancestor harbored resentment and suddenly unleashed a secret technique in an attempt to escape. However, the Void Returning Realm puppet suppressed him, preventing his escape.

The Black Demon Ancestor struggled in vain and roared, "Yang Hongbo, if you kill me today, the Black Demon Sect will not let you go!"

Yang Hongbo coldly said, "Black Demon Ancestor, you have violated my alliance without cause today, and your crime is unforgivable. Even if the Black Demon Sect comes to retaliate, I, Yang Hongbo, will not be afraid." After saying that, he waved his hand, and a sword aura shot towards the Black Demon Ancestor. In the end, he and the Void Returning Realm puppet joined forces to kill the Black Demon Ancestor.

Upon seeing their sect leader dead, the Black Demon Sect cultivators fled in panic, only to be defeated and killed one by one by the Alliance members. The Alliance members cheered with joy, for the crisis was finally over.

After this battle, the alliance's strength was further enhanced, and its reputation became even more renowned. Under Yang Hongbo's leadership, the massive city alliance, centered on the Yang family and surrounded by the Zhou, Wu, Zheng, and Wang families, firmly established itself in this wild land and began an even more glorious development.
